Technology and Information Technology


Teledistribution is a set of equipment that interacts by sending signals (data, voice, images, and text) to the receiver – recipient connected to a network.

This system of sharing information and equipment was the beginning of the so-called networks, which consisted of a group of interconnected computers that formed an environment or group of computers that only these computers can access and not any other.

For this reason, computer networks have been developed with the aim of linking up with each other and taking advantage of these bases in an indistinct way to the sole requirement of those who request and need them.
Networks have become a fundamental element of what is called the Information Society.

A network is defined as an interconnected system of elements or persons. Interconnection allows the capacities of the elements to be enhanced. Conceiving society through the structure of networks has become a new way of thinking about reality. Networks are expanding at all levels in contemporary society, as they have proven to be effective forms of organization, enabling flexibility and at the same time resilience.

The installation of a computer network (also called an information network) aims to meet the agency’s computer communication needs and make the best use of resources. Such use allows reducing operating costs (telephone, mail, transportation, courier, etc.). The number of peripherals required is also reduced, as several computers share, for example, the same printer on a network and it is not necessary for each machine to have its own printer.


Depending on how you transmit, there are two types of networks:

If the data and information circulating on the network can only be interpreted by machines (e.g. computer network), then it is a “digital network” The term digital, in the same way, involves discrete input/output values. Something discreet is something that can take fixed values. In the case of digital communications and computing, these values are 0 (zero) and 1 (one) binary.

However, if this network is shared by machines and people (e.g. the telephone network), then it is an “analog network”. The analog term in the telecommunications and computing industry means the entire input/output process whose values are continuous. A continuous thing is anything that can take an infinite number of values within a certain limit, upper and lower.
A device called a modem (modulator and demodulator) transforms analog signals into digital and vice versa.

Also depending on what they are used, there are other types of networks:

Data networks: like mobile phone networks are used for SMS, Internet, Voice over IP.
Video networks: like cable TV repeaters.
Audio networks: such as radio station repeaters.
Multimedia networks: these are companies that provide telephone, cable, and internet services simultaneously.
Depending on the type of technology used for the links, they can be microwave, satellite, fiber optic, power lines, etc.
